For anyone who grades Colab notebooks

Typed, or pasted?

Humanomics reads a Colab notebook's revision history and shows, in seconds, whether it grew line by line or arrived in big finished blocks.

The Humanomics dashboard: a score of 55 out of 100, five metrics and a growth chart
How it works

Two clicks. One answer.

A finished notebook looks the same whether it was written over a week or pasted in a minute. Its revision history doesn't.

1

Any notebook saved in Google Drive.

It reads the revision history for you through your existing Colab session.

Read the score

A 0–100 score, five metrics and the exact saves behind them.

Five signals

Tied to how fast people really type.

Faster than typing

Share of added code that arrived faster than 1,000 bytes a minute.

flag at 60%

Biggest fast block

The largest single addition that arrived that fast.

flag at 4 KB

Few big saves

Share of added code from the largest 10% of saves.

flag at 75%

Rewriting

Code removed for every byte added. Written code gets deleted and redone.

flag below 0.03

Code per hour

Net code added per hour of active work.

flag at 12 KB/h

A fast typist enters about 200 characters a minute, roughly 12 KB in an hour of nonstop typing. Code that arrives five times faster didn't come from a keyboard.

No false alarms from plots

Outputs don't count.

Colab saves charts and printed output inside the notebook file. Humanomics measures only the code and text in your cells.

A reason to ask. Not a verdict.

A high score means the history looks like bulk pasting. It doesn't prove AI wrote the code: pasting your own code or using Colab's Gemini looks the same.
